sIPHoN Specification of Letters Patent No.

To all 'whom 'it may concern:

Be it known that I, HENRY M. VALKER, of lVatei-town, in Litcheld countyand State of Connecticut, have invented a new and useful Improvement onSiphons, and do hereby declare 'that the following is a full and exactdescription thereof, reference being had to the annexed drawings, and tothe letters of reference marked thereon, making a part of thisspecification.

The nature of my invention consists of a device for the simultaneousopening and closing of the orices at each end of a siphon.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

I construct my siphon with an opening at the top, secured by a screwcap, as shown at A, the cap being lined with rubber, leather, or, othersuitable material, to make itair tight, and with valves, or other deviceat `each end, connected by a cord, chain, or

closing the valves. The water or other iuid is poured in at the top,till it is full, the cap is then secured in its place, and the siphon isready for use at any moment by inserting the short arm in water, andopening the valves, by lowering the ring C. The flow of water can beinstantly stopped or renewed, thus making it capable ot' being movedfrom vessel to vessel without the trouble of refilling at each transfer;and of measuring oli' any quantity of fluid.

My improvement enables me also to use siphons of a size hitheretounattainable from the difficulty of exhausting the air, and of operatingthem, thus making them of great use in the place of umes and givingincreased power.

I am aware that siphons have been iilled at the top, and that a valve orstop cock has been used on the long arm, but

Vhat I claim is- The application of a device for the simultaneousopening and closing of the orifices at each end of a Siphon.
